Where do you get the best Dim Sum in DC or Southern MD area?
Oriental East in Silver Spring is the best I've found in the metro area. It's been consistently good for many years now.

When you say Southern MD, do you mean south of PG County, along Rte 301, or do you mean Montgomery County? I don't know of anything down south, but MoCo has many fine choices.
Oriental East in SS is good, but I personally prefer New Fortune in Gaithersburg or Hollywood East Cafe on the Boulevard in Wheaton. Good Fortune, across the street from HECOTB in Wheaton, used to be good but is now a pale shadow of it's former self. Silver Fountain in Aspen Hill is also decent.
Nothing worth going to in DC proper.
We just went with another couple for dim sum to New Fortune, based on Chowhound's recommendations. Overall, I would say it was a very positive experience. They had many of the dishes we were looking for and the quality, if not on par with New York, was good. We loved the walnut shrimp which was something we had never tasted, before. (We went on Sunday around 12 and the place was hoppin' but we only waited about 5 minutes for a table.)
Hollywood East Cafe on the Boulevard, in Wheaton. (There are two Hollywood East Cafes up there-- I'm referring to the one on University Blvd.) This is some of the best dim sum I have ever had.
I used to go to Oriental East years (20+) ago, but I don't think it's very good anymore. I'm not a big fan of Hollywood East either. I have a friend in Waldorf who loves dim sum -- please report back if you find something good and closer than Wheaton! She comes up every so often for a fix at Good Fortune (which, yes, I know some people here don't like), but it's not really close.
